JERSEY, A .CORPOR.A.TION 0F BUCKET ATTACHMENT FOR CONVEYERS.

Specification of Letters Patent.

Patented Oct. 11, 1910.

Application filed March 4, 1910. Serial No. 547,370.

To all whom it may concern:

Be it known that I, FRANK B. BALL, a citizen of the United States,residing at No. 259 Sherman street, Passaic, New Jersey, have inventedcertain new and useful Improvements in Bucket Attachments for Conveyers,of which the following is a clear, full, and exact description.

This invention relates to conveyers, and the main object of the same isto provide an endless belt conveyer with a shield, or protecting medium,at a point under the bucket, whereby the belt is protected from abrasionor injury, due to the action of the bucket, when particles of coal,stone or other mate; rial accumulate between the bucket and the belt,and still other objects are to render conveyers of the described typemore efficient and durable.

These being among the objects of the invention, the same consists ofcertain features of construction to be hereinafter described and thenparticularly pointed out in the claims, with reference to theaccompanying drawings, showing a desirable form of the invention and inwhich- Figure 1 is a side elevation of a portion of a conveyer providedwith my improvement. Fig. 2 is an enlarged front elevation of a portionof my improved belt conveyer, looking toward one bucket, and Fig. 3 is aside view of the same parts.

Referring to the drawings, the belt 1 may be of any suitableconstruction and conducted over a pulley 2 in a wellknown manner. Thereis a pulley for the other end of the ordinarily endless belt.

It is found in practice with endless con veyer belts, provided withbuckets, that particles of coal, stone or other material find accessinto the spaces between the buckets and the belt, with the ultimateresult that abrasion and injury to the belt takes place due to thegrinding action produced by the said particles, which action is greaterin the region of the pulleys. It is my aim to overcome this objection,to which end there is located upon the belt, underneath the buckets 8,protecting spaced shields 4, preferably of thin sheet metal or othersuitable flexible material, adapted to protect the belt against injury,should particles of stone, coal or other like particles find access tothe spaces between the buckets and the belt. Each shield 4 is of agreater area than the area of the back of each bucket and s secured tothe belt preferably by means of rivets 5, and, as the said shield ispreferably flat, said rivets hold it flat upon the belt so thatthroughout its under-surface it contacts with the belt. The rivets passthrough all the edges of the said shield 4. A plurality of said shieldsare secured to the belt, so that there is one shield for each bucket,the intervals between the shields corresponding with the intervalsbetween the buckets. The buckets are secured to the belt in any desiredmanner, such as by means of extensions 6 of the backs of the buckets, sothat one end only of the bucket is attached, while the other end of eachbucket is free to permit said bucket being carried around a pulley.

Under the free end of each bucket there is secured to the said shield 4a transverse bar 7, which constitutes a strike-member or abutment forsaid free end of the bucket. Said shields 4 also obviously reinforce thebelt l underneath the buckets and prevent stretching or distortion ofthe belt at the points under the buckets. They also furnish reliablesupporting means for the buckets.

What I claim as new is:

l. In a conveyer, the combination of abelt, a bucket attached thereto atits upper end only, and a flexible shield secured to said belt betweensaid bucket and said belt.

2. In a conveyer, the combination of a belt, a bucket attached theretoat its upper end only, and a flexible shield secured at its edges tosaid belt and located under said bucket.

3. In a conveyer, the combination of a belt, a bucket attached theretoat its upper end only, and a flexible shield secured to said beltbetween said bucket and said belt, and being of a greater area than thatof the back of said bucket.

4. In a conveyer, the combination of a belt,
